After reading several reviews on the Sumo Springs, I ordered a set for the front and back of my Class A Winnie Adventurer 35P.

I weighed it and adjusted the air pressure in the tires, installed a TruCenter on the front, had the front end aligned and installed a Blue Ox Track Bar on the rear. It drives a lot better but I am hoping for even more improvement.

I have been doing my own installations so I will be installing them myself in the next few weeks!

I installed them on my gasser, 35' Did not get my $$$ worth. Hope you have better results. A rear sway bar would be the way to go in my opinion and that would be my next thing except my rig handles quite well as it is.

The Sumo Springs come in two different setups. The less expensive set basically replaces the factory bump stops (about $500) and the other system has a lot larger Sumo Spring that is installed via brackets, etc and is about $1200 for the set. Which system did you install?

If you installed the heavy duty set and didn't see much improvement, it isn't too late for me to change my mind.

The shop couldn't get to me so I installed the rear units myself. Now to put the wheels back on. Discovered that one of the attachment brackets on my rear sway bar is broken so most likely that is the main problem with the side to side sway. Will fix today.

I installed them on my Itasca front & rear It did help with the ride smoothed out the bumps,was able to put them on without removing the rear wheels,one hole had to be drilled on each side but other than that they went on pretty easy.matched them up Koni's. I still might add a rear trac bar but am happy with the results.
